mbedtls/tests/suites/test_suite_x509parse.function
Gilles Peskine 1f186ff330 Add missing calls to USE_PSA_DONE 
Some functions were not deinitializing the PSA subsystem. This could
lead to resource leaks at the level of individual test cases, and
possibly at the level of the whole test suite depending on the order
and selection of test cases.
